These Celebrity mashups are so close it will really mess with your head. Some would suggest that one person’s face always dominates the other’s and we only end up seeing that one.
Others would say that the average face of a population is typically perceived as the most attractive, for biological reasons.. probably.
You could also argue that if you tried doing people that don’t look the same, like Andre the giant and Lindsay Lohan the results would be very different.
However you see it, these are pretty well-done I reckon!
